-The iodoform test or reaction is a chemical reaction where iodoform (CHI3) is produced by the multiple halogenation of a methyl ketone (a molecule containing the R-CO-CH3 group) in the presence of a base. R may be H, alkyl or aryl.The reaction can be used to produce CHCl3, CHBr3 or CHI3.thanal is the only aldehyde to give the iodoform reaction. Finally, OH- (aqueous) is added, which reacts with, for example, the triiodoacetone. CH3COCI3 + OH- â CHI3 + CH3COO-Iodoform, or triiodomethane (I3CH) is a pale yellow substance. It is therefore a solid at room temperature.
Iodized salt. Bob Ingelhart / Getty Images. Iodized salt is a form of table salt which has had iodine added to it to prevent a disease called goiter. Goiter is characterized by the swelling of the thyroid gland due to iodine deficiency.Iodine is a nutrient that usually occurs naturally in vegetables, which absorb it through the soil in which they grow. But a diet consisting of food grown in soil that lacks iodine can cause an iodine deficiency, leading to goiter.oiter is characterized by the swelling of the thyroid gland due to iodine deficiency.
